• Fuel and engine: Radium Engineering surge tank kit, port injection kit, coolant tank and PCV parts, and a COBB air oil separator.
• Exhaust: AWE Exhaust Suite, Borla cat-back and Scorpion downpipe.
• Suspension: HARDRACE sway bars, lower arms, bushings, braces, ball joints and camber and toe arms, RS-R springs and COBB motor mounts.
• Brakes and drivetrain: Alcon and AP Racing front big brake kits, a Wavetrac diff, Xtreme Clutch twin plate kit and COBB shifter parts.

• LW or LZ: most parts fit both, but a few, like Radium's Fluid Lock catch can, are listed for the LZ only. Check the title.
• ST or RS: Focus RS parts only fit the ST where the ST is named, as the RS has a 2.3L engine and all-wheel drive.
• Tune first: intercooler, downpipe and fuel parts need a matching tune. The COBB Accessport is the usual starting point.

Have a qualified workshop fit engine, fuel, suspension and brake parts. Get a wheel alignment after suspension work, and bleed and road-test the brakes after brake work. Load a tune to suit any engine change before driving hard.
